Architecture is a Knowledge Pyramid

Research Areas
Software Architecture, Programming Paradigms, Design and Descriptions,
Conceptualization and Ontology (from modeling point of view),
also Music and Languages

Recently, I have been looking into formal models for software architectures for effective and concise descriptions to represent the structure and behavior at architectural level, and then to reason about them.  Some of these involve exploring through  the abilities and limitations of the ideas of Petri and Milner, which can be considered as the two highly significant formal models for expressing software architectures and the phenomena that occur therein. One model is close to the traditional component oriented models expressed through the object oriented and component oriented paradigms, and the former is close to the process oriented world expressed through modern BPMN-like architecture models.
